Mossberg 590RM Stand-Off 12 Ga Shotgun – Proven Workhorse

Description

The Mossberg 590RM Stand-Off 12 Ga is a shotgun chambered in 12 Gauge with a 18.5-inch barrel and a 10+1 capacity. It comes with a parkerized barrel finish, a 5-pos adj stock w/interchangeable pad, moe pistol grip, compact forend (black) stock and a Picatinny rail for optics.

Mossberg 590RM Stand-Off 12 Ga Overview

This is a magazine-fed version of Mossberg’s 590 pump. Instead of a tube, it feeds from detachable double-stack magazines, so you can reload quickly by swapping magazines, a big advantage for training and competition.

Design and Features

It keeps the proven 590 action, dual extractors, and twin action bars, and adds a magazine well for detachable box magazines. The heavy-walled barrel and ambidextrous controls are carried over from the 590 line. This configuration has a parkerized barrel finish, a 5-pos adj stock w/interchangeable pad, moe pistol grip, compact forend (black) stock, a Picatinny rail for optics, and Cylinder Bore chokes.

Handling in the Field

A magazine-fed pump is fun at the range and quick to reload. With a loaded magazine it is heavier and taller than a tube gun, so it shines most for range and competition use.

Action and Trigger

The pump action uses twin action bars for smooth cycling, and the controls are easy to reach for either hand.

Sights and Optics

Mount the optic of your choice with quality rings or a mount, and zero it with the load you plan to use.

The 12 Gauge Cartridge

The 12 gauge is the most popular shotgun gauge in America, with the widest selection of loads for clays, upland birds, waterfowl, turkey, deer slugs, and home-defense buckshot.

Setup and Accessories

Set your shotgun up for its job: hunters will want a sling and a few choke tubes, clay shooters may add a recoil pad, and a home-defense setup benefits from a weapon light. Pattern every load and choke combination you plan to use.

Ownership Tips

Read the owner manual fully before your first range trip, and keep the manual, box, and receipt with your records for warranty service and resale. Unload the shotgun and confirm it is empty before cleaning. Field-strip it according to the owner manual, scrub the bore with a brush and patches, and wipe carbon from the action and choke threads. Apply a light coat of quality gun oil to the contact points, and wipe the exterior with a lightly oiled cloth before storage.

Product Notes

Shotguns are only as good as the load and choke you pair them with. Birdshot in the 7.5 to 9 range is right for clays and small upland birds, heavier shot sizes for pheasant and waterfowl, and buckshot or slugs for deer and home defense. Pattern the gun on paper at the distance you expect to shoot, and check that your shells match the chamber length stamped on the barrel.

State Laws

Magazine capacity limits, feature restrictions, and transfer rules vary by state and locality. Check your local laws before ordering, and ask your receiving dealer if you are unsure whether this configuration is legal where you live.
